Improvement in setting gems



IMPROVEMENT IN SETTING GEMS.

Specification forming part of Letters Patent No. 1 65,722, dated July20, 1875; application filed June 23,1875.

To all whom it may concern:

Be it known that I, THOMAS W. FRY, of the city and county of Providence,in the State of Rhode Island, have invented a certain new and usefulImprovement in Setting Stones in Jewelry; and I do hereby declare thatthe following specification, taken in connection with the drawingfurnished and forming part of the same, is a clear and correctdescription of my invention.

It is well known that a stone, as ordinarily mounted in the so-calledcrown or other open setting, ieceives and retains dirt during use. Asthe dirt to a great extent collects around the base of the stone withinthe setting, the brilliancy of the stone is temporarily impaired, ithaving a dim or cloudyappearance.

To remedy this defect, and retain the pleasing and desirable effect ofthe crown or other Open setting, is the object of my invention; and itconsists in the combination of a crown or other open setting with astone-receiving cup, whereby not only is the base of the stone protectedfrom accumulation of dirt, but at the same time the article of jewelryto which the cup is applied possesses the general exterior efi'ect orappearance of the ordinary crown or other open setting.

Referring to the drawing,- Figure 1 represents a view in perspective ofa shirt-stud embodying my invention. Fig. 2 represents detached views ofthe several parts thereof.

In the drawing I have illustrated my improvement as applied to ashirt-stud otherwise of common or ordinary construction. It

is to be understood, however, that my invention is applicable to variousarticles of jewelrysuch, for instance, as fin ger-rings, sleevebuttons,ear-rings, breast-pins, &c., of that general class in which stones aremounted in crown or other open settings.

The shirt-stud illustrated in the drawings is provided with acrown-setting, A. A stone is shown at B. C denotes a stone-receivingcup, such as I employ in combination with a crown or other open setting,as shown at A. In this instance the cup is provided with an annular heador flange, c, which is recessed upon itsinner surface. Thestone-receiving cup 0 is preferably made of the same material as thesetting, and is highly polished upon its exterior surface. Upon theinteriorof'the cup, and lining its entire surface, I sometimes place athin sheet of silver or tin foil, which secures a fine color for thestone. This use of foil, 850., has long been the practice of jewelers inmounting cheap stones in cup-settings. The stone is secured in positionby burnishing the inner edge of the bead or flange c. The cup with thestone is then placed within the setting, the several points of which arebent to clasp the edge of the cupflange 0, thereby securely holding itwith the stone in proper position.

It will be observed that the stone-receiving cup, thus employed incombination with a crown or other open setting, protects the base of thestone from dirt or similar matter, and at the same time the desirableexterior effect of the weltknown crown or other open setting isattained.

Having thus described my invention, I claim as new In a setting forstones of jewelry, the combination of a crown or other open setting witha stone-receiving cup, substantially as and for the purpose described.
